i am doing a 5 lug conversion on my 88 gx, do i need different front brake lines for the 4 pot brakes? all the way from the brakes to the master cylinder? the rear ones fit no problem.

 

Dont think you need the lines all the way to the MC. I think its just the first short section coming off the caliper. Mazdatrix.com has them for cheap, at the very bottom.

Im doing a 5 lug conversion soon and would like to know if these are what we need???
I cut the lines on my 5 lug,DOH.

 

you need the hubs, rotors, calipers,pads and lines that go from the wheel well to the caliper.

 

Yeah i have everything besides the lines.

Very bottom of the link above, are these the lines we need?

 

You don't need anything.
The longer hose from the single piston caliper will work fine with the four piston unit...no adapter or hard line needed.

Even if upgrading to braided stainless lines, I'd prefer the single piston hose as it eliminates one connection point in the system.

 

Sweet thats what i wanna hear. Doing the 5 lug swap this weekend, i even have unused stainless steel braided lines laying around that are for the single piston calipers. Thanks dude, later.

 

you sure? cuz when i tried to connect the single piston brake line to my 4pot caliper, the thread is too long

 

Crap, so back to this thread again. Where are the people who have done this swap before?

 

I've done this, my car has been running single piston lines on 4-piston calipers for several months.
If necessary, shorten the banjo bolt.
This type of connection seals with the crush washers instead of the taper at the fitting's end, so if the bolt is shortened enough, the washers can do their thing.

 

You can just add washers and not have to cut anything
